The Test–Retest Reliability and Predictive Validity of a Battery of Newly Developed Occupational Performance Assessments [link]Paper  doi  abstract   bibtex   
The purpose of the author in this study was to investigate the test–retest reliability and predictive validity of new occupational performance assessments. The researcher used a test–retest design with mixed quantitative and qualitative methods. The test–retest reliability of the perceived adequacy of engagement in occupations of priority to participants as measured on the assessments was r (15) ¼ .54, p \textless .05. Perceived test adequacy predicted 27% [B ¼ .517, t ¼ 2.18, R2 ¼ .27, F (1, 13) ¼ 4.75, p ¼ .048] and retest adequacy predicted 67% [B ¼ .820, t ¼ 5.16, R2 ¼ .67, F (1, 13) ¼ 26.61, p ¼ .000] of variability in the retest frequency of engagement in occupations seen as a priority by research participants. Test satisfaction scores predicted 50% of variability in the test frequency of engagement in occupations [B ¼ .707, t ¼ 3.61, R2 ¼ .50, F (1, 13) ¼ 13.01, p ¼ .003]. It was concluded that adequacy and satisfaction scores could be used by occupational therapists in planning therapeutic interventions to facilitate future performance of occupations seen as important by clients.
